IMPROVEMENT IN FABRICS FOR ROOFINQ.

Specification forming part of Letters Patent No. 36,4 S4, dated September 1'6, 1862.

To aZZ whom it may concern:

Beit known thatI, A. RoBrNsoN, of the city, county, and State of N ew York. have invented a new and lImproved. Fabric to Serve as a Foundation to Receive Cement for Roofing Purposes; Aand I do hereby declare that the following is a full, clear,'and exact descrip tion of the same, reference beinghad to the accompanying drawings, making a part of this specification, in which- Figures l and 2 are face views of' a portion of fabric which constitutes 'my invention; Fig. 3, asecton of Fig.1, taken in theliue XX.

lSimilar, letters of reference indicate corresponding parts in the' severalligures.

The objectof this invention istoobtain a cheap'and durable fabric to be applied to the roots of buildings to receive'auy suit-able cement which may be used as water-proof covering. v

The invention is designed to `supersede canvasand other fabrics which have been hitherto used for the purpose, as well as paper` which has also been used without any special preparation, but has not proved to be durable.

The invention consistsin the employment or use of paper of any suitable kind, cut into strips of a proper width and twisted or folded in the form of twine'or cords, said paper cords being then Wove into afabric having both a warp and a filling or weft of the same material, or having one ofthe aforesaid parts of twine or cords formed of hemp, cotton, or other material. Y

The paper I prefer to use, in consequence of answering'a desirable purpose `and'being the `most ecnomical, Vis the ordinary thin brown or Mani-la paper, such as is corumonly' used for Wrapping up light wares and articles of merchandise. into strips'a, of any suitable width and length, and the strips are twisted slightly by any` proper means, so as to form cords b. These cords b may form both thewarp and the fill ing or weft of the fabric, andthe warp is adjusted orlitted in a loom and the filling or weft interwoven in the warp inthe same Way as any ordinary or .common textile fabric is produced. In Figs. 1 and 3 both Athe warp and filling or weft are shown formed'of the paper cords.

most desirable fabric; but a very valuable fabric for the desired purpose mightbe pro- This paper is cut 'This would probably be theduced by having the filling or weft formed ol paper cords, and the Warp formed of ordinary bjemp or cottou' twine, c; or cords of other tbe twine or cordsl aforesaid.

A11 ordinary loom of the simplest kind may be employed for weaving the fabric, andj a very sim-ple twisting apparatus would answer foi-'twisting the paper strips.

The, fabric 'thus produced'lforms a very strong and durable foundation-for receiving the various nements used for rooting purposes, While it is much less costly than canvas or strong muslin hitherto used. Ordinary unprepared paper is not at all durable; but ithas been used to some extent on the score of economy. By my invention a fabricis ob tained which will but.. slightly exceed in cost the simple unprepared paper and still be as durable as the cloth or canvas hitherto used forthe purpose. I

' The fabric thus made also has a considerable thickness or'body, so that where'covered with the cement a thicky roofing substance or Vmaterial is obtained, and one which will not crack in being handledand rolled up. The

interstices also' of the fabric serve to 4hold the cement, so'that it will 'not -shell or peel ott'. The ordinary paper and canvas or musliu foundations hitherto used are comparatively thin, and-a thick roofing' material cannot be obtained without applying avery heavy coating of cenienttbat will crack and shell oli'.

. By my invention the cement may be applied tothe foundationprcvious to its being ap plied to the roof, and the prepared roofing` may be sold in anysuitable quantities and then ,applied where desired, whereas theordiuary cement ro'otng requires that the paper or muslin be rst secured to' the roof and the cement put onl afterward, as the thin material will not admit ofgood lap joints beingformed.

I would remark that a very good paper cord may be madev by folding or gathering the' paper strips compactl y together an d` then compressing them by a roller vor rollers. In this case there would be no twist; but stillquite a good cord would beobtained by such modifcation. It, however, would besubstantially the same thingr as the slight twist given them,

as the ebjeeh'is to form the paper into cordsi k paper, or strips `of paper and twine woven in o'rdermhat they may be woven. together, and cement, substantially -esv herein otfdo not broadly claim the use of paper for shown and desrbed. e
